Good luck on your choice, 2 desirable pieces to choose between but as many on this forum will agree - VINTAGE RULES ! ;-)
Just to re-cap : i think the leather strap is probably original but the bracelet is not applicable to this model.
The bracelet may be an item you could re-sell , especially if its Heuer signed. ( i must add i would myself be interested to buy it should it turn out to be stamped Heuer on the clasp )

(please tell me you have Depeche Mode's "Enjoy the Silence" in your play list, a definite favourite of mine . By the way i already have tickets for their concert this summer)
Good luck for your upcoming wedding
